Sound & Audio

Sound Mixer IssuesNot so much an issue, as a general question.
Is there a mod or update that will allow you to select which audio output device a program will use? I know some programs allow you the prioritize outputs, similar to Skype, but I am an avid fan of ... "home videos" and it would be rather embarrassing...
